Nuclear quantum effects and nonlocal exchange-correlation functionals applied to liquid hydrogen at high pressure.

Abstract

Using first-principles molecular dynamics, we study the influence of nuclear quantum effects (NQEs) and nonlocal exchange-correlation density functionals (DFs) near molecular dissociation in liquid hydrogen. NQEs strongly influence intramolecular properties, such as bond stability, and are thus an essential part of the dissociation process. Moreover, by… (More)
